APC20-470K-RC

Fixed Inductors Overview

The APC20-470K-RC is a fixed power inductor manufactured by Allied Components International. It features an inductance of 47 µH with a tolerance of ±10%. The component utilizes an axial package configuration and is designed for power choke applications. Key electrical specifications include a maximum DC resistance (DCR) of 50 mΩ and a saturation current rating of 1.28 A. These parameters define its performance characteristics within electronic circuits requiring reliable energy storage and filtering capabilities.

Fixed Inductors Feature Summary

• Axial leaded construction for through-hole mounting
• Designed as a power choke for energy storage
• Low DC resistance for efficient power handling

Fixed Inductors Applications

• Power supply filtering circuits
• DC-DC converter input/output stages
• General-purpose power electronics

Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm the exact DCR and current ratings, as these values are critical for circuit design. Ensure the axial package dimensions match the PCB layout requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer's part number to avoid confusion with similar series components.

Fixed Inductors Selection Notes

Select this component when a 47 µH inductance value is required with a 1.28 A current capacity. The axial package is suitable for applications where board space allows for through-hole technology. Consider the 50 mΩ DCR limit to ensure minimal voltage drop and heat generation. Verify that the operating temperature range meets the system's thermal requirements.

Fixed Inductors Part Context

This part belongs to the APC20 series of axial power chokes from Allied Components International. The series offers various inductance values and current ratings. The '470K' suffix indicates the 47 µH value and 10% tolerance. This series is distinct from radial or surface-mount inductors offered by the same manufacturer.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 47 µH inductance, 1.28 A current rating, and axial package. Check for equivalent DCR and saturation current specifications. Verify pin compatibility and mechanical footprint. Consult manufacturer cross-reference lists for verified alternative part numbers.
